A way to raise non-combat skills ICly

[Walrus Warwagon]

While we currently receive a lot of additional skill points during level-ups, the skill system is vast and increasingly utilized.

Perhaps allowing players to select a few non-invested skills that are non-combat or non-stealth to gradually improve over time would help expand the system.
Levels are lost and gained, but it would be nice to have some flavor skills grow independently of them and remain stable regardless of XP.
